Behold: the ultimate carry-on bag. According to Travel Pulse, pilots agree that one bag in particular soars miles above the competition.

BrightLine Bags aren't technically single bags — they’re “bag systems” with interchangeable sections that can be zipped or clipped together in every configuration you can think of. If you haven’t heard of them before, that’s because they’re designed specifically with aviation experts in mind, so you’re more likely to see them in the cockpit than in an overhead compartment. But if anyone knows the best way to fly, it’s pilots.

According to Travel + Leisure, BrightLine bags are as customizable as can be. Need a backpack for some trips? Zip on a back panel equipped with shoulder straps. Other accessories include handle choices and every hook and strap you can think of. Frequent travelers will also appreciate that they prioritize function over form. Every space, pouch, and pocket has a distinct function—from carrying your business cards to your camera.
